and in vme node,  iscsi volume show.

Disk /dev/sdc: 300 GiB, 322122547200 bytes, 629145600 sectors
Disk model: iSCSI Disk

Hello ByungJoon,
are you able to access (touch files,create tes dir) the /dev/sdc (iscsi lun) on Hypervisor host using non GFS2 filesystem (ext4 ) to be sure
that lun is fine.
Remove errored GFS2 from GUI.
Please check if there are already GFS2 signature exist.
#tune2gfs -l /dev/sdc
Wipeout the signature using dd or wipefs
#wipefs -a /dev/sdc
confirm using "lsblk -f"
Try adding from GUI again.

Hi @Ranveer,

we installed node1. what requirement need to configure GFS Datastore?

You do have a 3-node cluster in VME?  Only once you have a cluster of minimal 3 nodes, you can created a GFS2 datastore.
